Is it desireable, or even possible , to put an E145 into a 60s Fender Showman tonering cab ?? The frame is much bigger, will it physically fit ?? I've one cab with a E140, and one empty cab. I'm looking for something different. I have the 2 Showman heads, and have always loved the soundof them. They have plenty of power with the E140. Would the E145 be a lot lower in output ??
